BARIQ BRQ-9000SF – Pressure Independent Control Valve (PICV)
The BRQ-9000SF is a high-performance Pressure Independent Control Valve designed for precise flow regulation and stable hydronic balancing in HVAC systems. It integrates three functions in one compact unit:
Control valve for modulating regulation.
Differential pressure regulator for constant ΔP.
Balancing valve for preset flow limitation.
This ensures accurate flow control regardless of system pressure fluctuations, delivering higher energy efficiency and system reliability
